[patch v1 0/6] New Zhaoxin CPU vendor ID/FMS patch

by LeoLiu-oc

This set of patches is to add support for Zhaoxin Family 7 CPUs. With these patches, the kernel can identify Zhaoxin CPUs features and Zhaoxin CPU topology information. LeoLiu-oc (6): x86/cpu: Create Zhaoxin processors architecture support file x86/cpu: Remove redundant cpu_detect_cache_sizes() call x86/cpu/centaur: Replace two-condition switch-case with an if statement x86/cpu/centaur: Add Centaur family >=7 CPUs initialization support ck: x86/cpufeatures: Add Zhaoxin feature bits ck: x86/cpu: Add detect extended topology for Zhaoxin CPUs MAINTAINERS | 6 + arch/x86/Kconfig.cpu | 13 +++ arch/x86/include/asm/cpufeatures.h | 21 ++++ arch/x86/include/asm/processor.h | 3 +- arch/x86/kernel/cpu/Makefile | 1 + arch/x86/kernel/cpu/centaur.c | 47 +++++--- arch/x86/kernel/cpu/zhaoxin.c | 170 +++++++++++++++++++++++++++++ 7 files changed, 243 insertions(+), 18 deletions(-) create mode 100644 arch/x86/kernel/cpu/zhaoxin.c -- 2.20.1
